BRCA1, BRCA2, P53
30

It can determine if a lump is a fluid filled cyst or solid (and therefore possibly malignant)
31
What are the chemotherapeutic drugs available for breast cancer?
Tamoxifen (Nolvadex): An estrogens antagonist which blocks receptors, decreasing stimulating effects of estrogen on breast cells. Herceptin: A monoclonal antibody drug which retards the growth of the disease by causing cellular regression.
